IL 814TE

Overview

The IL 814TE is a general-purpose digital isolator manufactured by NVE Corp/Isolation Products. It features three channels with a unidirectional input-to-output configuration of 3/0. The device utilizes Giant Magnetoresistance (GMR) technology and provides an isolation voltage of 2500Vrms. It operates within a supply voltage range of 3V to 5.5V and supports data rates up to 110Mbps. The component exhibits a common-mode transient immunity of 100kV/µs, with maximum propagation delays of 15ns for both low-to-high and high-to-low transitions. It is housed in a 16-SOIC package and functions across a temperature range of -40°C to 125°C.

Feature Summary

• Utilizes GMR technology for robust signal transmission without requiring an isolated power supply.
• Provides high common-mode transient immunity suitable for noisy industrial environments.
• Supports high-speed data communication with minimal pulse width distortion.

Applications

• Industrial automation systems
• Power electronics control circuits
• Medical equipment signal isolation

Procurement Notes

Verify the specific suffix 'TE' against the manufacturer's official documentation to confirm packaging details and any functional variations. Ensure compatibility with the required operating temperature range and supply voltage specifications before integration into the design.

Selection Notes

Select this component when a three-channel isolator is required with high-speed performance and strong noise immunity. Consider the 16-SOIC package dimensions and surface-mount installation requirements during PCB layout planning.

Part Context

This part belongs to the IsoLoop family from NVE Corp/Isolation Products, which leverages GMR sensing technology. Unlike capacitive or optical isolators, these devices do not require isolated power supplies on the secondary side, simplifying system design while maintaining high reliability.
